Here’s an opinion piece from the Guardian a year ago- really good points: ‘Refereeing decisions are not the real problem here. The real problem is the ludicrously disproportionate attention devoted to discussing refereeing decisions. The number of actual injustices, as opposed to disagreements, is minuscule next to this overwhelming fog of rage. Let’s face it, people are the problem here. Like the block button on Twitter, like silent touchlines and anger management courses, VAR is just another attempt to cope with and soothe and manage their feelings of disempowerment and alienation. It is people’s rage that demands this, more than any meaningful search for objective truth. This is not cricket, where TV replays can establish the definite truth of angles and nicks. More than any other sport football constantly presses itself up against the limits of its own laws, relying on continual judgment calls simply to function at all. There is no objective truth in football. Instead the idea is to play the game at the very edge of what is defined as football and what is defined as foul, an interpretation of various physical movements that depends on the application of a set of descriptive words. What amounts to a grey area is itself a grey area. The areas for debate are always up for debate.
